Abstract

The invention discloses waterborne wood lacquer which consists of component A and component B, wherein, component A is obtained by dispersing and mixing deionized water, adipic dihydrazide, droxyethylcellulose, 215 titanium white powder, wollastonite powder, kaolin, 800-mesh heavy calcium carbonate and other raw materials; component B is prepared by dispersing and mixing water-based fluorocarbon resin, water-soluble acrylic resin, film-forming assistant and other raw materials. During use, component A and component B are mixed by the weight ratio of 1:1, and brush coating, roll coating and spray coating with the lacquer can be conducted after an appropriate amount of water is added to be stirred evenly. The waterborne wood lacquer of the invention is waterproof and permeable, has good weather and water resistant, strong adhesion force, and has excellent performance in particular in lustrousness and hydrophobicity.

Description

technical field [0001] The invention relates to a paint, in particular to a water-based wood paint for wood surface painting. The invention also relates to a preparation method of the water-based wood paint. Background technique [0002] Traditional wood paints are solvent-based paints. From the early phenolic paints, alkyd paints, nitro paints to the currently widely used polyurethane paints, they all contain a lot of volatile organic solvents, which release a lot of harmful pollutants during the production and use of paints. organic compounds (VOCs). With the restrictions on VOC and the increasing emphasis on environmental protection in various countries, solvent-based wood lacquers are facing unprecedented challenges. As a result, water-based wood lacquers emerged as the times require, and have become a hot spot for research and development by many scientific research institutes and paint manufacturers. [0003] Water-based wood paint is a kind of paint that uses water...
